Axiom QSFP+ to four SFP+ passive twinaxial direct attach cable, 6.6 ft

Axiom

Axiom QSFP-4SFP10G-CU2M-AX 40GBase-CR4 QSFP+ to 4 SFP+ Cable

SKU CH-J6X5-BXQSD

Splits a 40 Gbps QSFP+ port into four 10 Gbps SFP+ links over a 6.6 ft passive twinaxial cable

  • 40 Gbps aggregate bandwidth from one QSFP+ port
  • Four independent 10 Gbps SFP+ links over a single cable
  • 6 ft passive twinax reach for rack-to-rack connections
  • Ready-to-use direct attach with no transceivers required

QSFP+ to 4 SFP+ breakout cable

This passive direct-attach cable splits a single 40 Gbps QSFP+ port into four independent 10 Gbps SFP+ connections. It is built for rack-to-rack or switch-to-server links inside the same cabinet. The twinaxial construction keeps latency low without active electronics.

Passive twinax for short-reach 40G links

The 6.6 ft length suits adjacent rack connections where active optics would add cost and power draw. It handles four 10 Gbps lanes simultaneously, but cannot extend beyond the passive copper reach or support longer fibre runs. Buyers needing greater distance or active signal conditioning should choose a different cable type.

Questions about this item

Will this 40GBase-CR4 breakout cable let me keep my existing 10G SFP+ switches while adding a 40G QSFP+ uplink?

Yes, the cable splits a single 40G QSFP+ port into four independent 10G SFP+ connections so legacy 10G gear can stay in place.

How can I verify each 10G SFP+ leg is live after plugging the QSFP+ end into my 40G port?

Check the switch port LEDs or run `show interface status` on each SFP+ port; all four should report link up at 10G with no errors.
